How to setup LDOM redundancy for multiple Guest Domains connected to SAN
Posted on 2010-08-12
I have a T5240 server with 2 fiber channel cards. This server has two PCI buses, so I am looking into setting up two I/O domains -- one for each PCI bus. I am confused on how to setup the FC cards and multipathing to support multiple guest domains. If each I/O domain controls one FC card then I'm assuming multipathing can't be setup at the I/O domain level but I'm not sure it can be setup at the guest domain level either. In addition, if there are multiple guest domains then I'm assuming I would need NPIV to be able to use the same FC cards for all the guest domains. So how would this work? Without NPIV would I need a separate set of FC cards for each guest domain?
